agree the shock scheme might be sub optimal, but quite a few bikes are using the solution right now, MT03, Shiver, Kawi 650 twins and Ducati Paul Smart classic, last one i actually rode quite hard and it handled pretty well in my book.
at least the shock mount feeds the force quite straight into the frame tube,
frame is rob north-ish but not quite I think
the only question is how is this thing allowed into classic racing, if it is....
